I believe that applies to all microinverters from the M215 to the IQ8. The available power is additive as long as there is battery capacity and the micro inverters are not off due to the battery being at full capacity. If the battery is at full capacity, the IQ8 should still be able to supplement heavy loads, but others will not react fast enough if they have already been commanded off.
We always size our batteries alone to have sufficient power for the expected loads. Some people have asked if they can just use air conditioning during the day when the sun is shining and get a smaller battery. I decline to design systems that way. I believe it would be too unreliable.
